Nice fight, hopefully it will be on the main card. Matt Brown comes to bang, bro, and the FOX audience (if such a contingent truly exists) will remember him from the brutal KTFO of Swick. That same mythical audience would also enjoy seeing a guy with a red mohawk and badass tattoos - I'm not being sarcastic, I really mean that these guys are a nice combination of skills and spectacle, which is what a FOX card needs.
Sonnen-Bisping and Evans-Davis were important fights in terms of ranking and competitiveness (perhaps less so on Davis's part, but still), but they weren't remotely entertaining to anyone who just happened to switch the channel. I'm not saying FOX cards should just be full of "let me bang bro" / "just bleed" mismatches, but there's something to be said for placing value on entertaining match-ups - perhaps at least one fight per main card, to open the show with the aforementioned bang.
Lastly, this is a good match-up in terms of ranking (if you believe in ranking) - Brown was a .500 record guy, but is on a nice roll against low-to-mid-level competition. Hardy went on a dry spell but has rebounded nicely against the same level of competition that Brown has been winning against. Neither guy is going to come close to contendership in the wrestling-dominated Top 10 at WW, but both guys need a step up in competition, which is what this fight is.
